A load bank is a tool used to test transformers, which can simulate load conditions and measure the performance of the transformer. When using a load bank for transformer testing, you need to pay attention to the following aspects.

Choosing the right load bank for a specific power system application requires considering multiple aspects of the power system. Here are some key factors:
Load characteristics
Power requirements
Accuracy requirements
Control method
Other factors

When selecting an AC load bank, you need to consider several key factors to ensure that it meets the needs of the actual application.
1. Load power:
2. Load type:
3. Accuracy requirements:
4. Voltage and frequency range:
5. Adjustment method
6. Protection level:
7. Cooling method:

In today's highly intelligent power system, the stability of power supply equipment is directly related to industrial production, data security and even social livelihood. Qingdao Sunwin Technologies Co., Ltd. has been deeply involved in the industry for many years, with "accurate diagnosis and tailor-made" as the core, providing professional and customized load testing solutions for global customers.

1. Improve power factor and reduce loss
2. Stabilize system voltage
3. Improve the transmission capacity of the power grid
4. Improve the quality of power
5. Reduce equipment capacity requirements

Driven by the dual goals of global Industry 4.0 and "dual carbon" development, the manufacturing, petrochemical, metallurgical and other fields have put forward unprecedented requirements for the stability of power systems. According to the "2025 Global Industrial Energy Report", in power grids where new energy accounts for more than 40%, the power fluctuation range can reach 70%, while traditional load test equipment has low accuracy and slow response, resulting in an average annual power failure loss of more than 15% for industrial enterprises. With 29 years of technological accumulation, Sunwin Electric has launched an intelligent power load bank, which provides disruptive solutions for industrial power systems with the dual engines of "full-scenario adaptation + digital operation and maintenance".

Driven by the wave of digitalization, the scale of global data center construction continues to expand, but high energy consumption and heat dissipation issues have always been pain points in the industry. According to statistics, traditional air-cooled heat dissipation equipment accounts for about 40% of the total energy consumption of data centers, and its operating noise and inefficient heat dissipation capacity further restrict the green process. The 30kW liquid-cooled custom load bank launched by Sunwin Technology, with innovative liquid cooling and sound-proof technology as the core, provides a new solution for optimizing data center energy consumption.

The fuel cell test load is an electrical load used to simulate the actual working conditions of the fuel cell.

It is crucial to the performance evaluation and optimization of the fuel cell. To determine whether the fuel cell test load is damaged, a comprehensive evaluation can be conducted through the following aspects:

The future development trend forecast of load banks mainly includes intelligence, modularization, precise detection, environmental protection and energy saving, and multifunctionality.
